Definitions

  • the invention relates to an air spring, in particular for road vehicles and / or for rail vehicles, according to the preamble of claim 1 and a vehicle with at least one such air spring according to claim 6.
  • suspension systems can be used to dampen vibrations, depending on the application.
  • This also includes air suspensions, which utilize the compressibility of gases and, in particular, of air.
  • a widespread type of air suspension are air springs with a constant volume in the normal position.
  • the air is usually enclosed in a rolling bellows, which is connected airtight to other fitting parts such as in road vehicles with a cover or a flange plate and a rolling piston.
  • the piston is connected both to the lower end of the rolling bellows and usually to an axle in road vehicles or to a chassis in rail vehicles.
  • the upper end of the roll bellows is connected to a cover or a flange plate which is connected to the body or to the chassis of the vehicle.
  • the bellows is arranged between a sliding plate at the top and the piston at the bottom.
  • the bellows is slipped over the piston and rolls on it under pressure.
  • the air spring can be supplied with compressed air by a compressor so that, depending on the load, air can be pumped in or out to increase the filling volume and thus to keep the level of the vehicle constant.
  • Air springs of this type are used in various types of vehicles such as, in particular, road vehicles such as, in particular, trucks, trailers and omnibuses, as well as rail vehicles.
  • a buffer is usually attached inside the air spring and enclosed by the rolling bellows, the flanged plate and the piston, which is intended to ensure that the piston does not strike the flanged plate when the air suspension system is operated without air pressure or when it is overloaded.
  • the buffer is usually arranged, acting vertically, between the flanged plate and the piston on the piston, an arrangement on the flanged plate also being possible.
  • the buffer is usually made of rubber or plastic.
  • a rubber spring the so-called emergency spring
  • the rubber spring is usually arranged on the piston, although an arrangement on the sliding plate is also possible; in this case the sliding surface of the sliding plate is formed by the rubber spring.
  • the emergency spring can also be made of plastic instead of a rubber spring.
  • the flanged plate or the sliding plate In normal operation, due to excess air pressure in the air spring, there is a distance between the flanged plate or the sliding plate and the buffer or the emergency spring, which is used to cushion a chassis of a vehicle against, for example, an axle or, as in rail vehicles, against the bogie.
  • the buffer or the emergency spring is used for the primary suspension.
  • the flanged plate or the sliding plate is placed on the buffer or on the emergency spring. In this way, an emergency suspension is guaranteed, which also allows transverse movements of the flanged plate relative to the buffer or the sliding plate relative to the emergency spring.
  • the DE 10 2008 037 484 A1 shows such an air spring.
  • the emergency spring has a surface that is also designed as a sliding surface. It is also proposed that the surface of the sliding surfaces provide depressions for receiving lubricants. All of these measures serve to improve the sliding behavior and minimize wear on the sliding surfaces.
  • the flanged plate or the same plate comes into contact with the buffer or with the emergency spring even during normal use, for example during maintenance in the workshop or in the depot, where no corresponding air pressure is available, or but also in the case of defects in the air spring or compressed air supply.
  • the EP 1 541 386 A2 describes an air spring, comprising a rolling piston and a rolling bellows with a rolling fold that can be rolled on the wall of the rolling piston and at least one flat sensor element which can be actuated during the rolling movement of the rolling bellows and generates a height-dependent signal, the sensor element in the wall of the Rolling piston is integrated or is arranged on the side of the wall facing the cavity of the rolling piston.
  • the EP 2 792 516 A1 describes an air spring with a distance sensor, comprising: a signal receiving unit, a transmitting unit for electromagnetic waves and a magnetic signal transmission unit; wherein the signal transmission unit is configured to transmit a detected distance between the signal reception unit and the magnetic signal transmission unit to the signal reception unit, wherein the magnetic signal transmission unit further comprises an electromagnetic wave receiving unit and a converter for converting electromagnetic waves into electrical energy, and wherein the receiving unit for electromagnetic waves, receives electromagnetic waves transmitted from the electromagnetic wave transmission unit to operate the magnetic signal transmission unit.
  • the EP 2 724 877 A1 describes an air spring for a vehicle, comprising: a first fastening element for fastening to a vehicle chassis, a second fastening element for fastening to a movable part of a vehicle which is movable with respect to the chassis, a bellows which extends from the first fastening element towards the second fastening element extends and contains a volume of air, and a sensor arrangement, which is arranged in the volume of air.
  • the sensor arrangement is designed to detect at least one of a road condition, a vehicle condition and a payload condition.
  • the EP 3 006 891 A1 describes a distance measuring arrangement with a transmitting unit for emitting infrared, IR, light in the direction of a reference device, a receiving unit for receiving IR light reflected by the reference device, the receiving unit for receiving a first IR signal and a second IR signal is designed, wherein the distance measuring arrangement is designed to determine a distance between the distance measuring arrangement and the reference device based on the relative intensities of the first and second IR signals, which have different dependencies on the distance to be measured. Furthermore, an air spring is provided for a vehicle, the air spring having such a distance measuring device which is designed to determine a working stroke of the air spring.
  • the DE 197 01 530 C1 describes a device for determining the axial distance between two end members of a gas pressure spring with a gas pressure spring plate and a gas pressure spring piston, between which a flexible bellows is clamped, so that a space defined by the end members and the flexible bellows is created, the two end members in the axial direction of the gas pressure spring are movable to each other and an ultrasound transmitter is arranged on one end member and an ultrasound receiver is arranged on the other end member, with the aid of which the axial distance between the end members can be determined by detecting the transit time of ultrasonic pulses traveling from the ultrasound transmitter to the ultrasound receiver.
  • the EP 3 697 632 A1 describes a vehicle suspension assembly includes mounting brackets configured to be coupled to a vehicle frame assembly, trailing arms coupled to the mounting brackets, a first axle member coupled to the trailing arms, an air spring assembly coupled to the vehicle frame assembly, and one of the Trailing arm is coupled, wherein the first end, the second end and the air spring assembly cooperate to define an interior space, a second axle member that is spaced from the first axle member, a sensor assembly that is positioned in the interior space and configured to have a Senses operating parameters of the air spring assembly, and a control assembly operably coupled to the sensor assembly and configured to receive information from the first sensor assembly, the control assembly configured to have at least one operating characteristic of the second axle lied controls based on the information received from the sensor array.
  • the invention is based on the object of improving an air spring of the type described at the outset in such a way that impermissible wear on the inside of the air spring can easily be detected from the outside without dismantling the air spring.
  • the present invention thus relates to an air spring, in particular for road vehicles and / or for rail vehicles, at least having at least one first contact element and at least one second contact element, which are designed to be able to contact one another, as described above.
  • the air spring according to the invention is characterized in that at least one first transponder is embedded in the first contact element, which is spaced from the surface of the first contact element facing the second contact element by a first predetermined amount, or vice versa.
  • Such a transponder can be excited to emit a signal by means of a reader known per se, which signal can be detected by a reader. Only the presence of the transponder is of interest. If the wear on the first contact element rises above the predetermined level, the first transponder is also abraded and destroyed in the process. A corresponding query with the reader would then not give any feedback, so that it is immediately recognizable that the wear has reached or exceeded the predetermined level of the first transponder.
  • a user of such an air spring according to the invention can thus check whether the first transponder can still be recognized or not, without dismantling the air spring or removing it from the vehicle, by reading it out, which can be assessed as a defect or as impermissible wear. This can simplify maintenance and reduce maintenance and downtimes. This can also increase the safety of using the air spring.
  • At least one second transponder is embedded in the first contact element and is spaced from the surface facing the second contact element by a second predetermined amount, the first predetermined distance being smaller than the second predetermined distance.
  • This arrangement has the advantage that the signals from the first and second transponders can be distinguished when they are detected with the reader. In this way it is possible to determine the degree of wear and to differentiate between a warning level and an upper limit of wear. If the signal from the first transponder, which is located closer to the surface than the second transponder, is missing, this can be defined as a warning level. If the signal from the second transponder is also missing, this can be interpreted as reaching the wear limit.
  • the first transponder preferably and / or the second transponder, has an RFID transponder or is an RFID transponder.
  • This can simplify the implementation and use of a transponder, since RFID transponders are available cheaply, can be used flexibly and can have a low weight and / or a small size.
  • the first contact element is a buffer and the second contact element is a flange plate of the air spring, at least the first transponder, preferably and at least the second transponder, being embedded in the buffer.
  • the first contact element is an emergency spring and the second contact element is a sliding plate of the air spring, at least the first transponder, preferably and at least the second transponder, being embedded in the emergency spring. This can promote the implementation of the present invention on air springs for rail vehicles.
  • the present invention also relates to a vehicle with at least one air spring as described above, the air spring having at least one first contact element and at least one second contact element which are designed to be able to contact one another.
  • the vehicle is characterized in that at least one first transponder is embedded in the first contact element, that of the second contact element facing surface of the first contact element is spaced apart by a first predetermined amount, or vice versa.
  • the above figures are described in Cartesian coordinates with a longitudinal direction X, a transverse direction (not shown) oriented perpendicular to the longitudinal direction X and a vertical direction Z oriented perpendicular to both the longitudinal direction X and the transverse direction.
  • the longitudinal direction X can also be used as depth X
  • the transverse direction can also be called width
  • the vertical direction Z can also be called height Z.
  • Fig. 1 shows a schematic sectional illustration of an air spring 1 according to the invention according to a first exemplary embodiment.
  • Fig. 2 shows a section of the Fig. 1 .
  • An air spring 1 for rail vehicles is considered here.
  • the air spring 1 can also be referred to as an air spring device 1.
  • the air spring 1 has a piston 10 which is fastened to a chassis 2 of a vehicle, as in this exemplary embodiment of a rail vehicle.
  • a holder 11 is arranged on the piston 10 and holds a bellows 13 at its lower end radially on the outside.
  • the holder 11 can therefore also be referred to as a collar 11.
  • the bellows 13 is held at its upper end by a slide plate 14 which is connected to a body 3 of the vehicle.
  • an emergency spring 12 is arranged on top of the holder 11.
  • the emergency spring 12 has a rubber spring 12a and a sliding element 12b, which extend in this order from the holder 11 at the height Z upwards.
  • the sliding element 12b has a surface 12c in the form of a sliding surface 12c, which is directed upwards at the height Z.
  • the sliding plate 14 has a surface 14a in the form of a sliding surface 14a, which faces the surface 12c of the emergency spring 12 and is also located within the volume of the air spring 1.
  • the sliding plate 14 touches the emergency spring 12
  • the sliding surface 14a of the sliding plate 14 and the sliding surface 12c of the emergency spring 12 come into contact, which is why the emergency spring 12 can also be referred to as the first contact element 12 and the sliding plate 14 as the second contact element 14.
  • the contact can lead to abrasion of at least one of the two sliding surfaces 14a, 12c, which so far can only be recognized by inspecting these sliding surfaces 14a, 12c. This requires the dismantling of the air spring 1 in order to make the two sliding surfaces 14a, 12c in the interior of the bellows 13 accessible.

  • the erosion reaches an extent that corresponds to the distance A, the first RFID transponder 15 is exposed and is destroyed with further wear. A response from the first RFID transponder 15 is then no longer possible, so that when the air spring 1 is checked by an external reader (not shown here), the absence of the first RFID transponder 15 is noticeable. This absence can be defined as a warning level for wear.
  • the wear continues and removes material corresponding to the distance B of the original sliding surface 14a of the sliding plate 14, the second RFID transponder 16 is now also destroyed. During the check, the lack of feedback from the second RFID transponder 16 can be interpreted as the wear limit being reached.
  • the two transponders 15 and 16 can be of a very simple and small design, they are inexpensive and easy to embed in the sliding plate 14. In this way, a very simple and reliable wear detection is possible without dismantling the air spring 1 from the outside.
